Description

Die Erfindung betrifft ein Verschlusssystem für eine Filterklappe bei einer Industrieabsauganlage nach dem Oberbegriff der Patentanspruchs 1.The invention relates to a closure system for a filter flap in an industrial suction system according to the preamble of patent claim 1.

Stoffe, wie sie beispielsweise häufig in der Pharmaindustrie vorkommen, erfordern eine spezielle Vorrichtung, um eine Verteilung des Sauggutes und somit einen Kontakt mit dem Bediener und der Umwelt zu vermeiden. Durch den Einsatz von speziellen Industrieabsauganlagen mit hocheffizienten Absauglösungen wird eine sichere, saubere und produktive Arbeitsumgebung erreicht.Substances such as those often found in the pharmaceutical industry, for example, require a special device to prevent distribution of the suction material and thus contact with the operator and the environment. By using special industrial extraction systems with highly efficient extraction solutions, a safe, clean and productive working environment is achieved.

Für diese spezielle Absauganforderung wird häufig eine High-Containment-Filtereinheit eingesetzt, welche insbesondere für das Absaugen von gefährlichen Verbindungen und Substanzen geeignet ist. Mit dem Filtersystem wird erreicht, dass der gefährliche, krebserregende Staub, wie er beispielsweise bei Asbest oder bei pharmazeutischen Stoffen vorkommt, gegenüber der Umwelt gefiltert wird. Oberstes Ziel dieser Technologie ist es, jeglichen Kontakt mit den aufgenommenen, hochgefährlichen Stoffen zu vermeiden und somit den Bediener und die Umwelt vor möglichen Risiken zu schützen.A high containment filter unit, which is particularly suitable for the extraction of dangerous compounds and substances, is often used for this special extraction requirement. The filter system ensures that the dangerous, carcinogenic dust, such as is found in asbestos or pharmaceutical substances, is filtered against the environment. The main aim of this technology is to avoid any contact with the ingested, highly dangerous substances and thus to protect the operator and the environment from possible risks.

Der Filterwechsel erfolgt bevorzugt mit dem Bag-in-Bag-out-Verfahren. Das Wartungspersonal kommt hierbei während des Filterwechsels nicht mit dem kontaminierten Partikelfilter in Kontakt. Der in einem Beutel (Bag) versiegelte Filter kann über eine Filterdeckel bzw. eine Zugangstüre aus dem Gehäuse des Containmentsystems entnommen und dann entsorgt werden.The filter change is preferably carried out using the bag-in-bag-out method. The maintenance personnel do not come into contact with the contaminated particle filter when changing the filter. The filter, which is sealed in a bag, can be removed from the housing of the containment system via a filter cover or an access door and then disposed of.

Um die Wirkstoffe kontaminationsfrei ein- und ausbringen zu können, ist das System ferner mit einer RTP (Rapid Transfer Port)-Schleuse ausgestattet.The system is also equipped with an RTP (Rapid Transfer Port) lock so that the active ingredients can be introduced and removed without contamination.

Aus dem Stand der Technik sind Filterdeckel bzw. Zugangstüren für Industrieabsauganlagen bekannt, welche die Öffnung des Filtergehäuses bzw. der Schleuse luftdicht verschließen. Hierzu wird der lose Filterdeckel über ein Verriegelungsmittel mit dem Gehäuse verbunden. Das Verriegelungsmittel besteht meistens aus einer Schraubverbindung, wobei auf der Deckelseite bevorzugt vier Rändelkopfschrauben und auf der Gehäuseseite, die dazu passenden Gewinde vorhanden sind.Filter covers or access doors for industrial suction systems are known from the prior art, which seal the opening of the filter housing or the airlock in an airtight manner. For this purpose, the loose filter cover is connected to the housing using a locking device. The locking means exists mostly from a screw connection, preferably four knurled head screws on the cover side and the matching threads on the housing side.

Wesentlicher Nachteil bei solch einem Filterdeckel ist, dass dieser, nach dem Aufschrauben aller Rändelkopfschrauben, lose ist und mit beiden Händen gehalten werden muss. Der Deckel muss somit zuerst beiseite gelegt werden, um dann den Filter mit beiden Händen aus dem Filtergehäuse zu entnehmen.The main disadvantage of such a filter cover is that after all knurled head screws have been unscrewed, it is loose and must be held with both hands. The cover must first be put aside so that the filter can be removed from the filter housing with both hands.

Ein weiteres Problem ist, dass das Filtergehäuse generell einen umlaufenden Rand aufweist, welcher gegenüber der Gehäuseoberfläche absteht. Eine einseitige Schwenklagerung für die Filterklappe ist daher nicht möglich, da der Schwenkvorgang der Filterklappe durch den Rand behindert wird. Ebenso ist auch ein gerades Wegschwenken bzw. Anlegen der Filterklappe auf den Rand nicht möglich.Another problem is that the filter housing generally has a peripheral edge that protrudes from the housing surface. A one-sided swivel mounting for the filter flap is therefore not possible because the swiveling process of the filter flap is hindered by the edge. It is also not possible to swing the filter flap straight away or to place it on the edge.

Die DE 27 17 403 A1 offenbart eine Filtereinheit für eine Industrieabsauganlage mit den Merkmalen des Oberbegriffs des Anspruchs 1.The DE 27 17 403 A1 discloses a filter unit for an industrial suction system with the features of the preamble of claim 1.

Die DE 696 11 163 T2 offenbart ein modulares Luftreinigungssystem mit einer Zugangstür für den Zugang zu einer Filtereinheit. Die Zugangstür umfasst Gabelscharniere, bei denen ein Scharnierstift schwenkbar in einem Langloch der jeweiligen Gabelklemme geführt ist.The DE 696 11 163 T2 discloses a modular air purification system with an access door for access to a filter unit. The access door comprises fork hinges in which a hinge pin is pivotably guided in an elongated hole in the respective fork clamp.

Der Erfindung liegt deshalb die Aufgabe zugrunde, eine Filterklappe für eine Industrieabsauganlage so weiterzubilden, so dass ein einfacher Wechsel des Filterelementes möglich ist.The invention is therefore based on the object of developing a filter flap for an industrial suction system so that a simple change of the filter element is possible.

Zur Lösung der gestellten Aufgabe ist eine Vorrichtung durch den Gegenstand des unabhängigen Anspruches 1 gekennzeichnet.To achieve the object, a device is characterized by the subject matter of independent claim 1.

Die Filterklappe weist eine Kulissenführung auf, durch welche die Filterklappe einseitig schwenkbar an der Gehäuseoberfläche der Industrieabsauganlage angeordnet ist und ferner dadurch die Schwenkachse verschiebbar ausgebildet ist.The filter flap has a link guide, through which the filter flap can be pivoted on one side on the housing surface of the industrial suction system is arranged and thereby the pivot axis is slidably formed.

Ein erster wesentlicher Vorteil ist, dass der Benutzer beim Filterwechsel die Filterklappe nicht abbauen muss, sondern vielmehr als Arbeitsauflage für den Filter verwenden kann.A first major advantage is that the user does not have to remove the filter flap when changing the filter, but rather can use it as a work surface for the filter.

Durch die Anordnung der Filterklappe an der Gehäuseoberfläche mit einer Kulissenführung ist es nun möglich die Filterklappe von der Gehäuseoberfläche zu beabstanden und damit der notwendige Raum zu schaffen, welcher zum Abklappen der Filterklappe benötigt wird.By arranging the filter flap on the housing surface with a link guide, it is now possible to space the filter flap from the housing surface and thus to create the space required for folding the filter flap down.

Die Gehäuseoberfläche weist hierfür bevorzugt zwei Führungselemente mit jeweils einer profilierten Ausnehmung auf. Die Filterklappe hat zwei randseitige Stifte, welche in die profilierten Ausnehmungen einsetzbar sind und dort drehend und verschiebbar angeordnet sind. Die profilierte Ausnehmung dient somit als Kulissenführung, welche ein Beabstanden und Klappen der Filterklappe gegenüber dem Gehäuse erlaubt.For this purpose, the housing surface preferably has two guide elements, each with a profiled recess. The filter flap has two pins on the edge, which can be inserted into the profiled recesses and are rotatably and displaceably arranged there. The profiled recess thus serves as a link guide, which allows the filter flap to be spaced apart and folded relative to the housing.

Die Schwenkachse wird somit durch die beiden randseitigen Stifte der Filterklappe und die profilierte Ausnehmung des Führungselementes gebildet. Die Verschiebbarkeit der Schwenkachse erfolgt durch die relativ langen, profilierten Ausnehmungen der Führungselemente, welche die beiden randseitigen Stifte der Filterklappe führen und drehend lagern.The pivot axis is thus formed by the two pins on the edge of the filter flap and the profiled recess of the guide element. The pivoting axis can be moved by the relatively long, profiled recesses of the guide elements, which guide and pivot the two pins on the edge of the filter flap.

Das Abklappen der Filterklappe gegenüber der Gehäuseoberfläche erfolgt in einem Winkelbereich zwischen 45° und 135°, bevorzugt um 90°, so dass die Filterklappe als (Arbeits-)Tisch bzw. Ablage benutzbar ist. Die Kulissenführung dient somit sowohl als Scharnier, als auch als Klappbegrenzung für die Filterklappe.The filter flap is folded down relative to the housing surface in an angular range between 45 ° and 135 °, preferably around 90 °, so that the filter flap can be used as a (work) table or storage. The link guide thus serves both as a hinge and as a folding limiter for the filter flap.

Durch das Abklappen der Filterklappe in eine horizontale Position kann diese somit als Arbeitstisch bzw. Ablage für die Filtereinheit verwenden. Hierzu wird der Filter entweder alleine oder zusammen mit einer Unterlage (Tray) aus dem Filtergehäuse auf die heruntergeklappte Filterklappe gezogen. Dies stellt einen wesentlichen Vorteil gegenüber dem Stand der Technik dar, da der Filter ohne großen Aufwand und relativ einfach aus dem Gehäuse entnommen und anschließend von der Filterklappe gehoben werden kann.By folding the filter flap into a horizontal position, it can thus be used as a work table or storage area for the filter unit. For this, the filter is either alone or together with a base (tray) from the Pull the filter housing onto the folded-down filter flap. This represents a significant advantage over the prior art, since the filter can be removed from the housing with little effort and relatively easily and then lifted from the filter flap.

Die Schwenkachse der Kulissenführung verläuft hierbei horizontal zur (vertikal verlaufen) Längsachse der Industrieabsauganlage. Es ist jedoch auch möglich die Kulissenführung, sowie die damit korrespondierenden Stifte an der Filterklappe an den vertikalen, seitlichen Flächen oder an der oberen, horizontalen Fläche im Bereich der Gehäuseöffnung anzuordnen. Der Schwenkvorgang der Filterklappe erfolgt dann entweder nach links/recht oder nach oben.The pivot axis of the link guide runs horizontally to the (vertical) longitudinal axis of the industrial exhaust system. However, it is also possible to arrange the link guide and the corresponding pins on the filter flap on the vertical, lateral surfaces or on the upper, horizontal surface in the area of the housing opening. The filter flap is then swiveled either to the left / right or upwards.

In einer weiteren bevorzugten Ausführungsform ist die Kulissenführung an einer der Flächen der Filterklappe und der Stift an der Gehäuseoberfläche der Industrieabsauganlage angeordnet.In a further preferred embodiment, the link guide is arranged on one of the surfaces of the filter flap and the pin on the housing surface of the industrial suction system.

Bisher war es nicht möglich, die Filterklappe abzuklappen, da das Gehäuse der Industrieabsauganlage im Bereich der Gehäuseöffnung einen umlaufenden, kragenartigen Rand aufweist, so dass mit einem gewöhnlichen Klappscharnier ein Klappvorgang, sowie auch ein sicheres und genaues Aufsetzen der Filterklappe auf die Gehäuseöffnung nicht funktioniert hat.So far, it was not possible to fold down the filter flap, since the housing of the industrial suction system has a circumferential, collar-like edge in the area of the housing opening, so that a folding process and a safe and precise placement of the filter flap on the housing opening did not work with a conventional folding hinge .

Durch die besondere Ausbildung der Kulissenführung ist es nun möglich, die Filterklappe in einem ersten Abschnitt von dem Filtergehäuse zu beabstanden und anschließend in einem zweiten Abschnitt den Kipp- bzw. Klappvorgang durchzuführen. Entscheidend ist, dass bei allen Ausführungsformen die Filterklappe gerade bzw. parallel von der Gehäuseöffnung entfernt werden kann und anschließend gegenüber der Gehäuseoberfläche in einem Winkel von vorzugsweise 90° klappbar ist.Due to the special design of the link guide, it is now possible to space the filter flap from the filter housing in a first section and then to carry out the tilting or folding process in a second section. It is crucial that in all embodiments the filter flap can be removed straight or parallel from the housing opening and can then be folded at an angle of preferably 90 ° with respect to the housing surface.

In einer weiteren bevorzugten Ausführungsform ist unterhalb der Kulissenführung im Bereich der Gehäuseöffnung ein bügelartiger Tragrahmen angeordnet, welcher als Auflage für die abklappbar ausgestaltete Filterklappe dient. Der Bügel kann hierbei entweder fest mit dem Gehäuse oder auch lösbar verbunden sein. Ferner ist es möglich den Bügel zu klappen und in einer gewünschten Position bzw. Winkel zu arretieren.In a further preferred embodiment, a bow-like support frame is arranged below the link guide in the area of the housing opening, which serves as a support for the filter flap designed to be foldable. The bracket can either be fixed to the housing or detachably connected. Further it is possible to fold the bracket and lock it in a desired position or angle.

Darüber hinaus besteht die Möglichkeit, mindestens eine Feder zwischen der Filterklappe und dem Gehäuse anzuordnen, welche eine Kraft auf die Filterklappe während des Öffnungs- bzw. Schließvorgang ausübt.It is also possible to arrange at least one spring between the filter flap and the housing, which exerts a force on the filter flap during the opening or closing process.

Ferner ist es auch möglich, die Kulissenführung vertikal zu schwenken, so dass der Stift außer Eingriff bringbar ist. Im Anschluss daran liegt die Filterklappe lose vor und kann von der Industrieabsauganlage entfernt werden.Furthermore, it is also possible to pivot the link guide vertically, so that the pin can be disengaged. The filter flap is then loose and can be removed from the industrial extraction system.

Mit der Figur 1 wird eine Industrieabsauganlage 1 gezeigt, welche ein Filtergehäuse aufweist, das über eine Filterklappe 2 verschlossen bzw. verriegelt werden kann.With the Figure 1 an industrial suction system 1 is shown which has a filter housing which can be closed or locked via a filter flap 2.

Das Filtergehäuse beherbergt einen Filter 21, welcher beispielsweise als HEPA Filter 21 ausgebildet ist. Der Filter wird bevorzugt über einen Beutel entnommen (Bagln&BagOut-Verfahren). Die Filterklappe 2 wird mit den Verriegelungsmitteln 3 geöffnet und verschlossen.The filter housing houses a filter 21, which is designed, for example, as a HEPA filter 21. The filter is preferably removed via a bag (Bagln & BagOut process). The filter flap 2 is opened and closed with the locking means 3.

Bei den Verriegelungsmitteln 3 handelt es sich beispielsweise um Rändelkopfschrauben, welche mit Gewinden 18 im Bereich der Öffnung der Filterklappe 2 der Industrieabsauganlage 1 zusammenwirken.The locking means 3 are, for example, knurled head screws which cooperate with threads 18 in the area of the opening of the filter flap 2 of the industrial suction system 1.

Ferner geht aus der Figur 1 ein Bügel 4 hervor, welcher bevorzugt unterhalb der Filterklappe 2 angeordnet ist und zur Abstützung der geöffneten Filterklappe 2 dient.Furthermore goes from the Figure 1 a bracket 4, which is preferably arranged below the filter flap 2 and serves to support the open filter flap 2.

Die Filterklappe 2 ist bei der vorliegenden Ausführungsform nicht nur über die Verriegelungsmitteln 3 mit dem Gehäuse der Industrieabsauganlage 1 verbunden, sondern vielmehr auch über mindestens ein zusätzliches Füllungselement 7, welches eine profilierte Ausnehmung 8 aufweist. Die Ausnehmung 8 ist so ausgebildet, dass sie als Kulissenführung für einen Stift 13 dient.In the present embodiment, the filter flap 2 is not only connected to the housing of the industrial suction system 1 via the locking means 3, but rather also via at least one additional filling element 7, which has a profiled recess 8. The recess 8 is designed such that it serves as a link guide for a pin 13.

An der Filterklappe 2 sind bevorzugt zwei, hier nicht näher darstellte Stifte 13 angeordnet, welche in die Ausnehmungen 8 der Führungselemente 7 einsteckbar sind und von dieser geführt werden.Arranged on the filter flap 2 are preferably two pins 13, not shown here, which can be inserted into the recesses 8 of the guide elements 7 and are guided by the latter.

Mit der Figur 2 wird eine detaillierte Darstellung des Führungselementes 7 und dessen profilierten Ausnehmung 8 gezeigt. Oberhalb des Führungselementes 7 befindet sich das Verriegelungselement 3, welches als Rändelschraube ausgebildet ist. Bei der vorliegenden Ausführungsform wird die Filterklappe 2 mit insgesamt 4 Verriegelungsmitteln 3 mit dem Gewinde 18 der Industrieabsauganlage 1 verbunden. Selbstverständlich können auch weniger oder mehr als vier Verriegelungsmittel 3 zur Befestigung der Filterklappe 2 eingesetzt werden.With the Figure 2 a detailed representation of the guide element 7 and its profiled recess 8 is shown. The locking element 3, which is designed as a knurled screw, is located above the guide element 7. In the present embodiment, the filter flap 2 is connected to the thread 18 of the industrial suction system 1 with a total of 4 locking means 3. Of course, fewer or more than four locking means 3 can also be used to fasten the filter flap 2.

Mit der Figur 2 wird ferner ein Betätigungsmittel 5 gezeigt, welches einen Druckknopf 6 aufweist. Durch die Betätigung des Druckknopfes 6 wird eine nicht näher dargestellte Sperrklinke betätigt, wodurch der Stift 13 freigegeben wird und somit entlang der Ausnehmung 8 des Führungselementes 7 verschiebbar ist. Die Sperrklinke kann hierbei federbelastet ausgebildet sein.With the Figure 2 An actuating means 5 is also shown, which has a push button 6. By pressing the push button 6 one is not actuated pawl actuated, whereby the pin 13 is released and is thus displaceable along the recess 8 of the guide element 7. The pawl can be designed spring-loaded.

Die Sperrklinke greift im verriegelten Zustand in eine Ausnehmung der Gehäuseoberfläche 14 ein und sichert somit die Filterklappe 2 gegen ein unerwünschtes Verrutschen innerhalb der Ausnehmung 8 des Führungselementes 7.In the locked state, the pawl engages in a recess in the housing surface 14 and thus secures the filter flap 2 against undesired slipping within the recess 8 of the guide element 7.

Wird nun das Betätigungsmittel 5 in Richtung der Gehäuseoberfläche 14 verschoben, so öffnet sich kurz die Sperrklinke, um anschließend in die Ausnehmung der Gehäuseoberfläche 14 einzugreifen. Der Druckknopf 6 dient somit zur Entriegelung des Betätigungsmittels 5.If the actuating means 5 is now displaced in the direction of the housing surface 14, the pawl opens briefly in order to then engage in the recess in the housing surface 14. The push button 6 thus serves to unlock the actuating means 5.

Die Neuerung ist nicht auf die Verwendung eines Druckknopfes und einer Sperrklinke beschränkt. Es ist selbstverständlich auch möglich, dass der Stift 13 frei innerhalb der Ausnehmung 8 des Führungselementes 7 verschiebbar angeordnet ist.The innovation is not limited to the use of a push button and a pawl. It is of course also possible for the pin 13 to be freely displaceable within the recess 8 of the guide element 7.

Mit der Figur 3 wird die Industrieabsauganlage 1 in der Seitenansicht dargestellt. Die Filterklappe 2 ist mit den Verriegelungsmitteln 3 verschlossen, wobei sich im unteren Bereich der Filterklappe 2 das Führungselement 7 befindet, welches ein scharnierartiges Abklappen der Filterklappe 2 gegenüber der Industrieabsauganlage 1 ermöglicht.With the Figure 3 the industrial suction system 1 is shown in a side view. The filter flap 2 is closed with the locking means 3, the guide element 7 being located in the lower region of the filter flap 2, which enables the filter flap 2 to be hinged down relative to the industrial suction system 1.

Unterhalb des Führungselementes 7 ist ferner der tragrahmenartige Bügel 4 angeordnet, welcher eine abstützende Funktion für die Filterklappe 2 im geöffneten Zustand hat.Below the guide element 7, the support frame-like bracket 4 is also arranged, which has a supporting function for the filter flap 2 in the open state.

Die Figur 4 zeigt eine detaillierte Darstellung des Führungselementes 7 in der Seitenansicht. Das Betätigungsmittel 5 weist einen Druckknopf 6 zum Freigegeben des Stiftes 13 auf. Mit der Betätigung des Druckknopfes 6 wird eine Kraft auf die Sperrklinke ausgeübt, wodurch die Sperrklinke aus der Ausnehmung der Gehäuseoberfläche 14 herausgeschwenkt wird und somit der Stift innerhalb der Ausnehmung 8 des Führungselementes 7 frei bewegbar ist.The Figure 4 shows a detailed representation of the guide element 7 in a side view. The actuating means 5 has a push button 6 for releasing the pin 13. With the actuation of the push button 6, a force is exerted on the pawl, as a result of which the pawl comes out of the recess the housing surface 14 is pivoted out and thus the pin is freely movable within the recess 8 of the guide element 7.

Die Figur 5 zeigt die Industrieabsauganlage 1 mit einer teilweise geöffneten Filterklappe 2. Um die Filterklappe 2 zu öffnen, müssen in einem ersten Schritt die Verriegelungsmittel 3 gelöst werden.The Figure 5 shows the industrial suction system 1 with a partially open filter flap 2. In order to open the filter flap 2, the locking means 3 must be released in a first step.

Im Anschluss daran kann nun die Filterklappe 2 in Fallrichtung 15 von der Gehäuseoberfläche 14 der Industrieabsauganlage 1 weggezogen werden. Es erfolgt ein geführter Ziehvorgang der Filterklappe 2 aufgrund der Stifte 13, welche in den profilierten Ausnehmung 8 der Führungselement 7 verlaufen.Following this, the filter flap 2 can now be pulled away from the housing surface 14 of the industrial suction system 1 in the direction of fall 15. There is a guided pulling operation of the filter flap 2 due to the pins 13 which run in the profiled recess 8 of the guide element 7.

Die Ausnehmungen 8 der Führungselemente 7 sind dergestalt ausgebildet, dass zuerst nur ein relativ gerades bzw. horizontales Abziehen der Filterklappe 2 in Pfeilrichtung 15 möglich ist. Dies verhindert ein Verklemmen zwischen der Innenseite der Filterklappe 2 und dem Rand des Filtergehäuses 11. Des Weiteren werden die umlaufenden Dichtungen im Randbereich 11 nicht beschädigt.The recesses 8 of the guide elements 7 are designed such that only a relatively straight or horizontal pulling off of the filter flap 2 in the direction of the arrow 15 is possible at first. This prevents jamming between the inside of the filter flap 2 and the edge of the filter housing 11. Furthermore, the circumferential seals in the edge region 11 are not damaged.

Insbesondere bei Industrieabsauganlagen 1 ist für die Filterklappe 2 ein umlaufender Rand 11 im Bereich des Filtergehäuses vorgesehen. Dadurch kann die Filterklappe 2 nur gerade auf die Gehäuseoberfläche 14 aufgesetzt werden.In particular in industrial suction systems 1, a peripheral edge 11 is provided in the area of the filter housing for the filter flap 2. As a result, the filter flap 2 can only be placed straight onto the housing surface 14.

Nachdem nun die Filterklappe 2 in Pfeilrichtung 15 entlang der Ausnehmung 8 des Führungselementes 7 abgezogen wurde, ist ein Klappvorgang in Pfeilrichtung 9 der gesamten Filterklappe 2 möglich. Die Ausnehmung 8 des Führungselementes 7 hat daher eine Doppelfunktion. Zum einen wird ein gezieltes Abziehen bzw. Entfernen der Filterklappe 2 von dem Rand des Filtergehäuses 11 erreicht und zum anderen kann die Filterklappe im Anschluss daran abgeklappt werden.Now that the filter flap 2 has been pulled off in the arrow direction 15 along the recess 8 of the guide element 7, a folding process in the arrow direction 9 of the entire filter flap 2 is possible. The recess 8 of the guide element 7 therefore has a double function. On the one hand, a targeted removal or removal of the filter flap 2 is achieved from the edge of the filter housing 11 and, on the other hand, the filter flap can then be folded down.

Gemäß der Figur 5 kann die Filterklappe 2 bis zum Aufliegen auf den Bügel 4 abgeklappt werden. Im geöffneten Zustand ist somit eine Öffnung der Filterklappe 2 gegenüber der Gehäuseoberfläche 14 mit einem Winkel von 90 Grad möglich. Die Figur 6 zeigt eine detaillierte Darstellung der Filterklappe 2 bei einer Bewegung in Pfeilrichtung 15. Ausgehend von einer Position 16 in welcher sich die Filterklappe 2 in ihrer Schließstellung befindet, wird nun das Betätigungsmittel 5 in Pfeilrichtung 15 gezogen bis eine Position 17 erreicht ist. Im Bereich der Position 17 ist nun ein ausreichender Abstand zwischen der Filterklappe 2 und der Gehäuseoberfläche 14 erreicht, so dass ein Abklappvorgang in Pfeilrichtung 9 stattfinden kann.According to the Figure 5 the filter flap 2 can be folded down until it rests on the bracket 4. In the open state, an opening of the filter flap 2 relative to the housing surface 14 is thus possible at an angle of 90 degrees. The Figure 6 shows a detailed illustration of the filter flap 2 during a movement in the direction of the arrow 15. Starting from a position 16 in which the filter flap 2 is in its closed position, the actuating means 5 is now pulled in the direction of the arrow 15 until a position 17 is reached. In the area of position 17, there is now a sufficient distance between the filter flap 2 and the housing surface 14, so that a folding process in the direction of the arrow 9 can take place.

Mit den Figuren 7 und 8 wird eine vollkommen geöffnete Filterklappe 2 gezeigt. Gemäß der Figur 7 liegt die Filterklappe 2 auf dem Bügel 4 auf, welcher die Filterklappe in einem 90 Grad Winkel gegenüber der Gehäuseoberfläche14 hält.With the Figures 7 and 8 a completely open filter flap 2 is shown. According to the Figure 7 the filter flap 2 rests on the bracket 4, which holds the filter flap at a 90 degree angle with respect to the housing surface 14.

Anhand der Figur 7 ist ferner der Rand 11 des Filtergehäuses zu erkennen, welcher einen Abstand 10 gegenüber der Gehäuseoberfläche 14 der Industrieabsauganlage aufweist. Der Abstand 10 entspricht hierbei im Wesentlichen dem geraden Streckenabschnitt des Führungselementes 7. Dies geht ferner aus der Figur 8 hervor, welche noch einmal den Verlauf 12 des Stiftes 13 der Filterklappe 2 im Bereich des Führungselementes 7 bzw. dessen Ausnehmung 8 zeigt.Based on Figure 7 the edge 11 of the filter housing can also be seen, which is at a distance 10 from the housing surface 14 of the industrial suction system. The distance 10 essentially corresponds to the straight section of the guide element 7 Figure 8 which once again shows the course 12 of the pin 13 of the filter flap 2 in the region of the guide element 7 or its recess 8.

Der Stift 13 ist hierbei fest an der Filterklappe 2 angeordnet und wird innerhalb der Ausnehmung 8 des Führungselementes 7 geführt. Ausgehend von der Position 16, in welcher die Filterklappe sich in ihrer Schließstelle befindet, wird nun bei einem Öffnungsvorgang der Filterklappe 2 der Stift 13 in horizontaler Richtung (Pfeilrichtung 15) mit einem Abstand 10 von der Gehäuseoberfläche 14 der Industrieabsauganlage weggezogen. Der Abstand 10 entspricht somit der Tiefe des Randes des Filtergehäuses 11.The pin 13 is in this case firmly arranged on the filter flap 2 and is guided within the recess 8 of the guide element 7. Starting from position 16, in which the filter flap is in its closing position, the pin 13 is now pulled away in a horizontal direction (arrow direction 15) at a distance 10 from the housing surface 14 of the industrial suction system when the filter flap 2 is opened. The distance 10 thus corresponds to the depth of the edge of the filter housing 11.

Nach dem geraden Streckenabschnitt der Ausnehmung 8 folgt ein 45° Grad geneigter Abschnitt, welcher den Stift 13 gegenüber der Horizontalen schräg nach unten führt. Während bzw. danach kann dann die Filterklappe 2 in Pfeilrichtung 9 geklappt werden.After the straight section of the recess 8 is followed by a section inclined at 45 °, which leads the pin 13 obliquely downwards with respect to the horizontal. The filter flap 2 can then be folded in the direction of arrow 9 during or after.

Die Neuerung ist nicht auf die Anordnung eines Bügels 4 beschränkt. Vielmehr können hierfür auch andere Verriegelungselemente bzw. Schieber oder dergleichen zum Feststellen der Klappe auf einem gewissen Winkel eingesetzt werden.The innovation is not limited to the arrangement of a bracket 4. Rather, other locking elements or slides or the like can also be used for locking the flap at a certain angle.

Mit den Figuren 9 und 10 wir die Industrieabsauganlage 1 mit geöffneter Filterklappe 2 gezeigt. Anhand der Figur 9 lässt sich erkennen, dass die Filterklappe 2 im Innenraum eine gewisse Tiefe aufweist, welche in etwa der Tiefe des Abstandes 10 des Randes des Filtergehäuses 11 entspricht.With the Figures 9 and 10 the industrial suction system 1 is shown with the filter flap 2 open. Based on Figure 9 it can be seen that the filter flap 2 has a certain depth in the interior, which corresponds approximately to the depth of the distance 10 of the edge of the filter housing 11.

Ferner lässt sich aus der Figur 9 erkennen, dass die Gehäuseoberfläche 14 insgesamt vier Gewinde 18 für die Verriegelungsmittel 3 aufweist.Furthermore, from the Figure 9 recognize that the housing surface 14 has a total of four threads 18 for the locking means 3.

Figur 10 zeigt noch einmal das Führungselement 7 mit der kulissenartigen Ausnehmung 8, wobei oberhalb des Führungselements 7 das Gewinde 18 zur Befestigung der Filterklappe 2 mit dem Verriegelungselement 3 dargestellt ist. Figure 10 shows again the guide element 7 with the slot-like recess 8, the thread 18 for fastening the filter flap 2 with the locking element 3 being shown above the guide element 7.

Mit den Figuren 11 und 12 wird eine weitere, bevorzugte Ausführungsform der Filterklappe 2 für eine Industrieabsauganlage 1 gezeigt. Die Filterklappe 2 weist hierbei bevorzugt im Randbereich mindestens ein Scharnier 20 auf, mit welchem eine Verlängerung 19 in Form eine Tabletts ausgeklappt werden kann. Durch die besondere Ausbildung der Verlängerung 19 als Tablett ist es nun möglich, die Filterklappe als relativ großen Arbeitstisch zu verwenden, was insbesondere bei einem Filterwechsel des Filters 21 notwendig sein kann.With the Figures 11 and 12 Another, preferred embodiment of the filter flap 2 for an industrial suction system 1 is shown. The filter flap 2 preferably has at least one hinge 20 in the edge region, with which an extension 19 in the form of a tray can be folded out. Due to the special design of the extension 19 as a tray, it is now possible to use the filter flap as a relatively large work table, which may be necessary in particular when the filter 21 is changed.

Anhand der Figur 12 lässt sich ferner erkennen, dass der Arbeitsbereich der Filterklappe 2 deutlich um die Verlängerung 19 erweitert wurde.Based on Figure 12 it can also be seen that the working area of the filter flap 2 has been significantly extended by the extension 19.

Bei den oben beschriebenen Ausführungsformen ist stets vom Öffnungsvorgang der Filterklappe 2 die Rede. Selbstverständlich kann die neuerungsgemäße Ausführungsform auch beim Schließvorgang der Filterklappe 2 eingesetzt werden.In the embodiments described above, the opening process of the filter flap 2 is always mentioned. Of course, the embodiment according to the innovation can also be used during the closing process of the filter flap 2.

Durch die besonders profilierte Ausnehmung 8 ist es daher möglich die Filterklappe 2 an den Rand des Filtergehäuses 11 zu klappen und im Anschluss daran, die Filterklappe 2 gerade (entgegen der Pfeilrichtung 15) auf den Rand 11 aufzuschieben, so dass die Filterklappe 2 mit den Verriegelungsmitteln 3 an der Industrieabsauganlage 1 befestigt werden kann.Due to the specially profiled recess 8, it is therefore possible to fold the filter flap 2 onto the edge of the filter housing 11 and then to flip the filter flap 2 straight (against the direction of the arrow 15) onto the edge 11 postpone so that the filter flap 2 can be fastened to the industrial suction system 1 with the locking means 3.
